What is the “open area” of a vessel?
An open area means all deck areas, including coach roofs, superstructures, open flying bridges, trampolines and nets but excluding areas within a rigid deck house, a rigid cabin, a rigid half cabin or a securely enclosed under deck space. In the case of a vessel without a deck, open area means the whole vessel excluding areas within a rigid cabin or a securely enclosed space. In the case of kayaks or canoes, open area means the whole vessel.
